Question

A milk tank is in the shape of cylinder with hemisphere of same radii attached to both ends. If the total height of the tank is 6m and the radius is 1m. Calculate the maximum quantity of milk filled in the tank in liters. And also calculate the total surface area of the tank​

Answer 1

first find out the combined volume ie. volume of the cylinder + 2×volume of the hemisphere.

then find out the TSA of the figure ie. CSA of the cylinder + 2×CSA of the hemisphere.

Answer 2

Answer:

volume of cylinder =

$\pi {r}^{2} h$

=22/7 × 1 × 6

=132/7

=18.875

18.875 litre milk

total surface area =

$2\pi r(h + r)$

=2×22/7 × 1 × (16 +1)

=44/7 ×17

=748/7
